Python
We tried to make it as simple as possible to report the data you need to analyze your app usage and improve it.
This module is compatible with Python 3+.
Installation
1
$ pip install nucleus-python
Copied!
Basic usage
Add the following code to import Nucleus and init the analytics.
Don't use the
import ... from syntax as you won't be able to set the module options like app_id.1
import nucleus
2
3
nucleus.app_id = 'your app id'
4
5
nucleus.set_props({
6
'version': '0.5.0', # Set app version (Nucleus cannot detect it)
7
'userId': 'richard_hendrix'
8
})
9
10
nucleus.app_started()
Copied!
Only use
app_started() once per session, if you are using Nucleus in several files call app_started() the earliest possible.Options
You can init Nucleus with options:
1
nucleus.report_interval = 20 # interval (in seconds) between server com
2
nucleus.disable_tracking = False # completely disable tracking
3
nucleus.debug = False # Show internal logs to help debug
4
nucleus.auto_user_id = False # Assign the user an ID
Copied!
Identify users
You can track specific users actions on the 'User Explorer' section of your dashboard by assigning an user ID.
It can be any value as long as it is a string.
1
nucleus.set_user_id('someUniqueUserId')
Copied!
Alternatively, set the
auto_user_id option of the module to True to automatically assign the user an ID based on his username and hostname.Modify automatic data
You can overwrite some properties or fill data that wasn't detected.
You have to do it before calling
app_started() for this to workIt is a good idea to set your app version directly as Nucleus cannot detect it for the moment.
1
nucleus.set_props({
2
'version': '0.5.0',
3
'locale': 'en_US'
4
})
Copied!
Track custom data
You can also add custom data along with the automatic data.
Those will be visible in your user dashboard if you previously set an user ID.
The module will remember past properties so you can use
nucleus.set_props multiple times without overwriting past props.Properties can either numbers, strings or booleans. Nested properties or arrays aren't supported at the moment.
1
nucleus.set_props({
2
"age": 34,
3
"name": 'Richard Hendricks',
4
"job": 'CEO'
5
})
Copied!
To overwrite past properties, set the second parameter to
True.1
nucleus.set_props({
2
"age": 23
3
}, True)
Copied!
Errors
To catch errors with Nucleus, simply add the tracking code to an exception and pass the exception as the unique parameter.
Nucleus will extract the relevant informations and show them in your dashboard.
1
try:
2
my_app()
3
except Exception as e:
4
nucleus.track_error(e)
Copied!
Add this at the outermost level of your code to handle any otherwise uncaught exceptions before terminating.
The advantage of except Exception over the bare except is that there are a few exceptions that it wont catch, most obviously KeyboardInterrupt and SystemExit.
Events
After initializing Nucleus, you can send your own custom events.
1
nucleus.track("PLAYED_TRACK")
Copied!
They are a couple event names that are reserved by Nucleus:
init, error: and nucleus:.You shouldn't report events containing these strings.
Tracking with data
You can add extra information to tracked events, as an object.
Properties can either numbers, strings or booleans.
Nested properties or arrays aren't supported at the moment.
Example:
1
nucleus.track("PLAYED_TRACK", data = {
2
"trackName": 'My Awesome Song',
3
"duration": 120
4
})
Copied!
Toggle tracking
This will completely disable any communication with Nucleus' servers.
To opt-out your users from tracking:
1
nucleus.disable_tracking()
Copied!
and to opt back in:
1
nucleus.enable_tracking()
Copied!
This doesn't persist after restarts so you have to handle saving the setting.
